Kirby's (NYSE:KEX) stock is up by a considerable 40% over the past three months. As most would know, fundamentals are what usually guide market price movements over the long-term, so we decided to look at the company's key financial indicators today to determine if they have any role to play in the recent price movement. Specifically, we decided to study Kirby's ROE in this article.

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors' money. Put another way, it reveals the company's success at turning shareholder investments into profits.

How To Calculate Return On Equity?

ROE can be calculated by using the formula:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for Kirby is:

7.9% = US$252m ÷ US$3.2b (Based on the trailing twelve months to March 2024).

The 'return' refers to a company's earnings over the last year. That means that for every $1 worth of shareholders' equity, the company generated $0.08 in profit.

Why Is ROE Important For Earnings Growth?

So far, we've learned that ROE is a measure of a company's profitability. Depending on how much of these profits the company reinvests or "retains", and how effectively it does so, we are then able to assess a company's earnings growth potential. Assuming everything else remains unchanged, the higher the ROE and profit retention, the higher the growth rate of a company compared to companies that don't necessarily bear these characteristics.

A Side By Side comparison of Kirby's Earnings Growth And 7.9% ROE

When you first look at it, Kirby's ROE doesn't look that attractive. Next, when compared to the average industry ROE of 10%, the company's ROE leaves us feeling even less enthusiastic. In spite of this, Kirby was able to grow its net income considerably, at a rate of 25% in the last five years. We reckon that there could be other factors at play here. Such as - high earnings retention or an efficient management in place.

We then compared Kirby's net income growth with the industry and found that the company's growth figure is lower than the average industry growth rate of 48% in the same 5-year period, which is a bit concerning.

Earnings growth is an important metric to consider when valuing a stock. What investors need to determine next is if the expected earnings growth, or the lack of it, is already built into the share price. Doing so will help them establish if the stock's future looks promising or ominous. Is KEX fairly valued? This infographic on the company's intrinsic value has everything you need to know.

Is Kirby Making Efficient Use Of Its Profits?

Kirby doesn't pay any regular dividends currently which essentially means that it has been reinvesting all of its profits into the business. This definitely contributes to the high earnings growth number that we discussed above.

Summary

In total, it does look like Kirby has some positive aspects to its business. Specifically, its fairly high earnings growth number, which no doubt was backed by the company's high earnings retention. Still, the low ROE means that all that reinvestment is not reaping a lot of benefit to the investors. That being so, a study of the latest analyst forecasts show that the company is expected to see a slowdown in its future earnings growth.
